REVEGETATION RECOMMENDATIONS Summary: The revegetation recommendations should include methods to save existing topsoil, ground preparation, slopes, mulching specifications, seed and method of seeding, fertilization, and maintenance follow up. Topsoil: Although the present topsoil is limited in depth, it rill cork as a medium for plant growth. As explained by Cliff Thorne the topsoil is presently being stockpiled and used as the revegetatian process continues. A cover of topsoil 4 - 6" in depth with the present material could be used. I would also leave all rocks in the soil on the area to be reseeded. The rocks rill act as moisture retainers by s'nading small areas, and provide areas xhere the grass seed xill be protected from adverse conditions. The rocks will also blend in with the present landscape. Slopes: 6rhere possible, the slopes that are to be revegetated should be kept at a 3:1 or flatter. IP this is not possible the soil should be left at an angle close to the natural angle of repose for the soil. (l~ -1 or 2 - 1). Since the area to be revegetated will not cover a large portion of the mine site, the slopes should be left rough enough to prevent water from concentrating and causing gully erosion. 'there eater Prom an adjoining slope Trill cross the slope to be revegetated, a small berm oa grade should be constructed to exit the water to an area which is vegetated and the possibility of erosion is lessened. Ground Preparation: Areas to be reseeded should have Q - 6" of topsoil (use soil on site) applied. The top- soil should be applied to a roughened surface to prevent slippage and to form a better bond between the overburben and the soil. Afulching: I strongly recommend a mulch be placed over the area that is seeded. A straw mulch or an application of manure is clod form will help retain moisture, protect new seeding, minimize high intensity storm impact and prevent serious wind erosion. If straw mulch is used it is recommended that 70 - 90 lbs. of straw hay/100'sq. ft, be used. After the hay is applied it should be crimped into the soils with a crimper with strainght discs. Fertilization: Just before the seedbed is to be final graded an appl.icatioa of fertilizer to aid plant establish- ment should be applied. A fertilizer with a high nitrogen high phosphorus content should be used (30-20-5). The fertilizer should be spread at a rate of 1 lb/1000 sq. ft. :;
